NASCAR allowed them because they were stock on a truck.. A sedan delivery was licensed in many states as a truck. Hence stock part. The “real” stock parts (pos) had a hard time holding up under the rigor of racing..funny that Chevrolet was the only one who needed to do this…
Almost... I don't know the details of how they worked, but these contraptions burned/cooked wood or coal to extract the volatile gasses, which were then used as fuel for the engine. They must have run like crap, but during WW II, anything was better than nothing. I hope someone on here knows more about them and can explain how and how well they worked.
Pat Flaherty was a "500" winner, got hurt, came back, had a couple of good runs, and ended up in this MRC / Peterson Spl. at Milwaukee in 1963. Later he owned a bar in Chicago and raced pigeons (and won). The following year, Chuck Arnold drove the car at Indianapolis missed the starting field.
